Check_MK Werk 5022: Fixed timperiod history calculation

ID: 5022 Title: Fixed timperiod history calculation Component: Livestatus Level: 1 Class: Bug fix Version: 1.5.0i1 The parsing of the monitoring history had a bug, expecting an incorrect "TIMEPERIOD_TRANSITION:" instead of the correct "TIMERPERIOD TRANSISION:", which could lead to incorrect availibility calculations later (when the Nagios core is used).
